which are riveted to the center sills 1* in the same manner as the angles 6.

In mounting th tank onthe underframe, with this modified'structure, substantially the same manner of alinement is followed as described in connect-ion with the structure shown in Figs. 2, 3 and 4', the plates 5' being first riveted to the bottom sheet 2} of the tank 2, the tank then being placed on its saddles 3 and the plates 5' and 6' being riveted together. It will also be noted that this method of connection of the tank to the underframe being located between the underframeand the tank, but above the horizontal the horizontal plane of the sheet 2 of the of riveting tools and, in fact, with this construction it is possible to mount the tank on the underframe and then use suitable perforating tools for perforating the cast-.

ings 5 and upwardly projecting angles 6 to receive the rivets so that the tank may be located in its final position on the underframe before fit is'finally secured by rivets. Having thus described my inventiomthe following is what I claim as new therein and desire to secure by Letters Patent 1. In a tank car, a tank supported at or near its ends on the car underframe to permit expansion or contraction of its metal, and a pair of: saddles rigidly secured to said tank and the underframe approximately at the longitudinal center of the car.

2. In a tank car having anunderframe and a tank, a saddle or cradle member riveted directly to said tank and means riveted directly tothe underframe and to said saddle or cradle member for securing the tank to the undcrframe.

3. In a .t'ank car having an underframe and a tank 'in combination with means for supporting said tank, of a saddle or cradle member riveted directl to the tank and means rivetedxto the un erframe and to said saddle or cradle member for anchoring the tank to the underframe.

4. In a tankcar'having an underframe and a tank, in combination with means for supporting the tank at its ends, a longitudinal saddle or cradle member having a depending portion, and longitudinal means plane of the underframe and below riveted to the underframe andthe depending portion of said saddle or cradle member 'for anchoring the tank to the underframe.

5. In a tank car having an underframe and a tank, in combination with means for supporting a tank on its ends, a longitudinal saddle or cradle member having a depending portion and a longitudinal angle member riveted to the underframe and to the depending portion of said saddle or cradle member for anchoring the-tank to the underframe.

6. In a tank car having an underframe and a tank, a saddle or cradle member riveted directly to said tank and an anchoring member riveted to the underframe, overlapping said saddle orcradle member and riveted thereto:

7. In a tank car, an und'erframe and a tank in combination with'anchoring means secured to the underside of the tank and anchoring means secured to the underframe above the latter, the last mentioned means being secured to the first mentioned means.

8. In atank car, the combination with an underframe and a tank mounted thereon, of anchoring means on each side of and near the longitudinal center of the car and rigidly secured to said tank and the underframe.

9. In a tank car, the combination with an undcrframe and a tank mounted thereon, of an anchor means on each side of and near the longitudinal center of the car rigidly secured to said tank and said underframe, each anchor means being independent of the other, and a discharge nozzle located between th'e two anchor means.

10. In a tank car, the combination with an underframe and a tank mounted thereon, of a tank supporting and anchoring saddle on each side adjacent the longitudinal cen ter of the car, each saddle being ri idly secured to the tank and to the un erframe and each saddle comprising an upper portion and a lower portion riveted to said upper portion for the purpose of permitting a fine adjustment of the tank to the underframe.

In testimony whereof I aifix my signature in presence of two witnesses.
